The Orfordness Lighthouse, in Suffolk, is 10 meters from the sea after the gap halved over the past four years. Nicholas Gold, of the Orfordness Lighthouse Trust, said a ￡10,000 appeal had been set up [l]for urgent repairs. Storms forecast for this week pose a "real risk" of causing "significant damage" to the lighthouse. "If the work is not carried out in the next few weeks, the lighthouse will, in all likelihood, not be standing in a year’s time," said Mr. Gold.
    The lighthouse was purchased by Mr. Gold three years ago from Trinity House, the country’s general lighthouse authority. The Trust has spent ￡20,000 upholding the sea defences over the past two years. But it said a long-term solution was necessary involving building a steel wall around the front of the lighthouse and its outbuildings—at a cost of about ￡190,000.
